Eclipse editor performance has been getting incredibly sluggish for me. Scrolling a few lines can take 30 seconds, and typing text can take several seconds per character. It's driving me nuts, and seems to effect all the plugins (basic text editor, PyDev, XML Schema editor, Java, etc). How do I fix this?

I read about modifying my eclipse.ini to increase available memory parameters. I have 8 GB of total system memory, and even with Eclipse really dragging, I find not even half of my memory is in use.

My current eclipse.ini is:


Note, most are the defaults and all I specifically added was -Xms1024m and -Xmx1024m.

Are there any problems with my configuration? What else can I do to increase performance?

When did this begin happening? Do you have very large libraries loaded or lots of project dependencies? Do you have lots of plugins enabled? Are you using custom code formatting/coloring? Are you using a particular SDK? Because I've run Eclipse on lots of different machines with far less memory, and I've never experienced much sluggishness from either the Aptana PHP/JS perspectives or the Java perspective with GPE. – Lèse majesté May 14 '12 at 16:03
Also, this SO question is probably relevant. And you might try using TPTP to profile your various Eclipse plugins to see which ones are hogging memory (or if that's even the problem). – Lèse majesté May 14 '12 at 16:11
@Lèsemajesté, It's really always happened to some extent. Seems to grow worse the longer I have Eclipse open. – Cerin May 14 '12 at 16:50
That sounds like a memory leak. You might be able to use Memory Analyzer (MAT) to see which plugin is the culprit. – Lèse majesté May 14 '12 at 16:56
